Q: Transistor selection doubt on the transistor effect on the circuit?
A: Yes , you are able use any transistor with a larger power rating than the 2N4401 , provided that such also has an sufficient Ft for the operation frequency . The Ft is necessary for be around 5-ten times the operation frequency . The particularities of whatever transistor that you select will naturally have a spectacular effects on the circuit designing . Use a Smith chart to devise the input and output matching networks was later verify the performance of the circuit using Pspice . Be persuaded that your extran elements can handle the power , including , in particular , the RF choke if you use one . Be conscious that Pspice will not say to you if an element 's going to burn out or not , it is assumed that everything continues its to work no matter what .
Q: Why transistor is called a transistor?
A: transistor . This word is a blend form of transfercircle of resistor . The legs of transistor ( collector , emitter , basis ) transfer the resistance . So it 's called as transistor
